BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 457,041, dated August4, 1891. Application filed March 13, 1891. Serial No. 384,891. (Nomodel.) i

To all, whom it may concern:

Be it known that we, ELLIOTT M. BONNELL and JOHN SyLAi/nsme, citizens ofthe United States, residing at Corry, in the county of Erie and State ofPennsylvania, have invented certain new and useful Improvements inBed-Bottoms; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an improvement in spring bed-bottoms, and thenovelty will be fully understood from the following description andclaims when taken in connection with the annexed drawings, in which-Figure 1 is a plan view of a series of conical springs with ourimprovements applied. Fig. 2 is a side view of one of the springs,showing the improvement in connection therewith.

Referring by letter to said drawings, A indicates conical springs. Thesesprings, which may be of the ordinary construction, have the base orlargest whirl connected by a marginal spiral wire and parallellongitudinal spiral wires arranged on two opposite sides in a mannersimilar to that shown in our Letters Patent, dated June 25, 1889, andnumbered 405,821, and the bottom is preferably made so as to hinge inthe sections similar to that in the patent referred to.

B indicates a spiral wire, there being one employed transversely of thebed-bottom at the small end of each set of conical springs A, andOindicates atransverse brace-wire, which also connects the small ends ofthe conical springs. l

D indicates the longitudinal spiral wires arranged at the top or smallend of the conical springs and also connecting said springs. Inconnecting these parts together we first form an eye or loop a on thesmall end of the conical spring A. We then pass said eyes up between thespirals of the wire D, so as to be disposed in about the center of oneof the spirals. We then secure said eyes within the spirals of the wiresby means of a hook 1), formed on opposite ends of the transversebrace-rods 0. hen these conical springs and longitudinal spiral wiresare thus connected by the transverse locking and brace rods or wires, wefurther secure the conical springs to the longitudinal spiral wires D bycarrying one or more of the spirals of said transverse wires through thewhirl at the top of saidconical springs and one or more coils of thelongitudinal spiral Wires D.

It will be observed and better seen by reference to Fig. 2 of thedrawings that the end of the conical springs having the eyes Ct are notcarried between the spirals or coils of the springs D, but passhorizontally through one or more of the coils of said springs beforebeing secured in such position by the locking and brace rods, and inorder to secure a more firm fastening to the parts and prevent lateraldisplacement or casual separation one of the connecting ends of saidbrace-rods is bent, as shown at c,'and passed through a coil din thesprings D before engaging the eye in the springs A, the free end of saidrod passing on the outer side of said coil cl, as shown.

The transverse rods 0 are bent about midway of their length in atransverse position, as shown at c, and this bent portion receives andsecures the eye on the" end of the intermediate conical springs, andalso passes through two of the coils of the longitudinal springs D, soas to secure the parts and connect them in a manner substantially thesame as at the opposite ends of said rods, and the transverse spiralwires B connect the top whirl of the conical springs A to thelongitudinal spiral wires D. By this construction the conical springsare positively prevented from disconnecting during use, and while thesprings are allowed to yield with respect to each other they are firmlysecured together and must move in sets transversely, so as to alwayspreserve as near as possible a uniform top surface to the bed-bottom.

Having described our invention, what we claim, and desire to secure byLetters Patent, is-

1. In a spring bed-bottom, the combination,

conical springs and one or more of the coils of the longitudinal spiralwires, substantially as specified.

2. A bed-bottom having conical springs connected at their small ends bylongitudinal spiral Wires and the connected portions connected in turnby transverse spiral Wires and a transverse brace-rod connecting thelongitudinal spiral wires and one end of the conical springs at theinterlocked portions, substantially as described.

3. A bed-bottom having a series of conical springs and transverse andlongitudinally-arranged spiral Wires connecting the small ends of thesaid springs, in combination with the I 5 bracing-Wire C, secured midwayof its length to one spring and spiral wire and also at its oppositeends to other springs and spiral wires, substantially as specified.

In testimony whereof We afliX our signatures, 20 in presence of twoWitnesses.
